Zabbix 6.2.1 - missing graph labels in latest data graphs

[gerald23]

Hi
I'm new to zabbix and just installed 6.2.1 on a new centos 9 stream using mariadb , following the instructions at https://www.zabbix.com/de/download?z...ysql&ws=apache
The installation was painless. After adding some hosts (i really like the autoregistration feature) collecting some data, I noticed all the graph labels seem to be missing when opening a graph from any hosts "latest data" view. On the dashboard (right on the screenshot) this does not happen:




Am I missing some fonts as some old threads suggest? Does the command

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

not install all required components?

Server and agent log are not showing any errors or warnings, neither does the browser console. I tried chrome, firefox and edge browsers all with the same result.


Thanks in advance

I had the same problem after upgrading to Rocky Linux 9.
It turned out that /usr/share/zabbix/assets/fonts/graphfont.ttf was a link to an invalid location, because RL moved the TTF files around.

ln -sf /usr/share/fonts/dejavu-sans-fonts/DejaVuSans.ttf /etc/alternatives/zabbix-web-font

fixed it.

Hello, i'm having the same problem. I installed Zabbix 6.2.1 on Oracle Linux 9 and Nginx. I updated all packages and My graphics also don't display the labels.

This isn't a Zabbix server (or agent) issue, it's a front-end issue. You want to check both your web server logs and (assuming you have them enabled) the PHP-FPM logs, to see if either of them have obvious clues to the problem.

Make sure you have all the PHP extensions loaded that are listed as required on the "Frontend" installation requirements page: https://www.zabbix.com/documentation...n/requirements.

Make sure you're not missing 'php-gd', 'php-bcmath', or 'php-mbstring'.

RHEL/CentOS 9 are pretty new, so it could also be a font package or name change, but I would think that "fontconfig" would have the necessary aliases in place. Not many people here are hosting their server environment on RHEL 9 yet, so you're kind of on the bleeding edge.

Thanks for the quick response, I moved to alma linux 8 and there the labels are shown as expected. I'm staying with rhel 8 for now.
